I have learned about jar's. I know the basic definition of the manifest file.I know that it gets created automatically and that it stores information like version number etc.
But I want to know following :
1.Is it possible to create manifest file manually, overwriting the default one created automatically?
2.What other information does the manifest file stores?
3.Will it be right to say that it is a metadata of the jar file.
4.What is the exact use of the Manifest file?
